Top Priorities (5)

Sorted by impact
Critical: 1

Content-Security-Policy header is missing

Without a CSP, a single XSS bug can exfiltrate everything your users type — including credentials.

Security › Security Headers
Critical: 2

Cookie 'incap_ses_1847_765661' is missing the Secure flag

A cookie without the Secure flag can leak over HTTP — in HSTS-protected sites, this is still a defense-in-depth gap.

Security › Cookie Security
Critical: 3

Cookie 'nlbi_765661' is missing the Secure flag

A cookie without the Secure flag can leak over HTTP — in HSTS-protected sites, this is still a defense-in-depth gap.

Security › Cookie Security
Critical: 4

Cookie 'visid_incap_765661' is missing the Secure flag

A cookie without the Secure flag can leak over HTTP — in HSTS-protected sites, this is still a defense-in-depth gap.

Security › Cookie Security
Critical: 5

HSTS header is missing

Without HSTS, a network attacker can downgrade the very first connection to HTTP and steal the user's session.

Security › Security Headers
What fixing these means. Your site has several issues that may be affecting user experience and business outcomes. The 5 security gaps leave your users exposed — modern browsers increasingly warn visitors about insecure sites. Addressing the critical issues below would have the most immediate impact on your user trust.
5 security gaps detected — browsers may warn visitors about your site.

Figures combine localized regulatory fine ceilings, search/conversion value priced against local CPC, and bandwidth waste estimates. Results depend on implementation quality and audience composition. Not legal or financial advice.

  • Page takes 20.1s to load
    Users abandon at ~3s — you're 17.6s over the 2.5s threshold
    → Optimize render-blocking resources, preload the hero image, and compress images
  • Page feels frozen for 614ms
    Clicks on the primary CTA are ignored while JavaScript runs
    → Break up long tasks; defer non-critical JavaScript to post-hydration
  • 3 form field(s) without a label
    Screen readers skip unlabeled fields; autofill can't identify them; checkout abandonment spikes
    → Associate every input with a visible <label for="…">; add autocomplete attributes
  • No HSTS header
    Returning visitors are briefly exposed to downgrade attacks on first request
    → Set Strict-Transport-Security: max-age=31536000; includeSubDomains
  • No Content-Security-Policy header
    Higher XSS blast radius — one compromised script can exfiltrate the checkout form
    → Ship a reporting-only CSP first, then enforce once violations are clean

Observations (2)

No build tool detected

A framework (Apple) was detected but no bundler was identified. The build tool may not be detectable from output patterns, or the site may use the framework's built-in bundler.

Complex technology stack detected

28 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
